The default is €.

Getting Started
This app always starts with the Meta Screen, because of the Save/Restore buttons.
Once you have some viable bill data, save it for later retrieval - see Meta below - meanwhile...
You can start with the Meter screen, or the Tariff screen:

  • See the Meter screen print on the right.
  • The process starts with your bill(s) in front of you for the correct input data. Transfer dates and readings to the meter screen.
  • Check that number of days agrees with the bill; you may have to use the "inclusive" toggle.
  • The "show more" button displays most of the tariff details here. You can alter them here but, at least initially, it is best to do the whole thing in the Tariff screen.
  • The bill totals shown here do NOT include discounts. Discounts and other data are shown on the Bill screen.
  • Where volume units are converted to kWh, the total can be shown with decimals, or rounded to an integer: see Meta.

  • See the Tariff screen print on the right.
  •  Check that all inputs are correct, particularly the Tier1/Tier2 limit data and the Standing Charges data. The Calorific Value is required unless the meter is in kWh (smart).
  • [If your Tier1/Tier2 limit is by Quarter or Year, there is a requirement to get the Split date correct. This is because the calculation involves the number of days in the relevant year. If this is a leap year an extra day may be involved!] The Split date is the last day of the previous tariff.
  • Where tariff details are not required, leave them as 0 or NONE.
  • All values here are net of VAT.
  • The split toggle shows detail for the dual tariff; dual tariffs are discussed in the Meta screen.
  • Discount entries can be created or destroyed here: up to 6 max.
  • Enter the number, type and effect [Net/Gross Current or Previous period]. You will be using only the current period, unless you have a dual tariff.
  • The number entered is net for a Net discount and gross for a Gross discount (exactly as on the bill).

  • See the Bill screen print on the right.
  • The lower section shows a simple bill, identical to Meter screen. There is however more detail concerning days, Tier1/2 and kWh calculations, in the gold section. Above that is the red section detailing discounts.
  • This print shows a dual tariff bill, so Previous/Current columns are on show. Yours will probably be only single columnar.
  • If there are discounts available then the SubD toggle, will subtract them and show the results in the top section.
  • Also the Bill screen displays key comparison fields: kWh/day and pence/kWh(Gross).
  • The top lines show the totals for the whole bill.
  • VAT is shown if applicable.
  • Comparison indicators kWh/day and Cost/kWh are shown at the top.

  • See the Meta screen print on the right.
  • There are some simple decisions to be made right from the start: what type of meter is this, do you want to round kWh to integers (usually yes), is the VAT 5%?
  • In the UK it is best to use 5% for VAT and press the Retain toggle.
  • You can Advance the bill by x months; use -x to retard the bill dates.
  • The same applies to the Increase meter usage field, which is in %.
  • Use the "Expand to Year" button if you want to see this bill scaled up. Bear in mind that the costs are not updated for you.
  • A Split date can be toggled into use here for dual tariff. This is used when one bill runs over 2 different billing periods. The date is the last day of the Previous Tariff. It is entered in the Tariff screen, after using the Split toggle [also available on the Meter screen with "show more"].
  • Split date can also be used to directly compare 2 tariffs, if you ensure that the two periods contain the same number of days. Look out for leap years!
  • Be aware that a split date year number may change, to suit the bill dates [UNLESS Retained].

  • VAT fields can only be removed from view IF they are Zero.
  • Allowance can be made for meter reading roll over. Just input the number of significant digits that the meter shows (normally 5). Please make sure that the number entered registers (and it is briefly displayed).
  • Once you have a viable bill, press the Save button. This takes you to the Confirm screen, where you can alter the headings to make the bill more memorable. [Details such as... bill total, inclusive or not, increased]. Confirm to save.
  • You can retrieve this bill any time, using the Restore button. This takes you to the Available Bills screen. Here you can press on the bill you want, Confirm it and then see it back in the main app.

  • See the Confirm screen on the right.
  • What you see are the basic details supplied by the app, when Saving. You should add whatever data you think is relevant, which will make the bill more memorable! You may end up with a number of bills and this is a way of distinguishing between them.
  • This is the same screen (with different data) for Confirming a Restore bill operation.
  • This is the same screen (with different data) for Editing a stored bill.
  • Press the confirm button to action whichever operation.

Available Bills
  • See the 2 Available Bills screens on the right.
  • You will be able to choose a bill here for Restoring - short press. Followed by the Confirm screen.
  • You can also Edit or Delete a bill here - long press. The Edit takes you to the Confirm screen. The Delete deletes IMMEDIATELY.
  • The screen on the right shows the menu option - to Delete All Bills. Use with extreme caution, there is NO Confirm screen!

  • This screen shows the literal version of this help page. There is a screenshot at the bottom of GasElectricityBill9 .
  • Select whichever topic you want when you are off-line and cannot get to this website!
